Light
Plant weeping cherry trees in full sun. Not only does abundant light help encourage prolific blooms, it also discourages fungal diseases. Plus, the sun filtering through the pretty pink blooms adds beauty to the garden.
Soil
Provide it with a good garden loam so that its soil will drain well. Weeping cherries need rich, well-drained soil and dislike soggy soil. Prevent root rot by amending the soil to ensure it drains well.
Water
The water needs of this plant are average. But for optimal results, keep its soil evenly moist during the growing season. Do not allow the roots to sit in soggy soil.
Temperature and Humidity
Weeping cherry tree is suited to neither the extreme cold of the far North nor the extreme heat and humidity of the deep South. However, it tolerates cold and heat better than most other ornamental cherry trees.
Fertilizer
Weeping cherry tree performs best in ground that is at least moderately rich. Feed it annually with a complete fertilizer in early spring. Follow label instructions exactly, since the proper amount to apply varies according to tree size. Applying too much fertilizer can burn your plant.
Pruning
Usually, the weeping cherry tree you buy will be the result of a graft. The top part of the tree (the “scion”) is the weeping part. The bottom part (the “rootstock”) is actually a Prunus avium and does not have weeping capabilities. Any shoots coming out of the rootstock are undesirable and should be pruned off immediately; your plant is diverting valuable energy away from the rest of the tree into these useless shoots, which are unattractive. Weeping cherries typically need little pruning, unless you find a dead branch. However, if disease becomes an issue, prune affected branches out, or selectively prune branches after flowering to increase airflow to help combat fungal disease.
Propagating Weeping Cherry Trees
Because your weeping cherry tree most likely is the result of a graft, taking a cutting from either the scion or the rootstock and rooting it for propagation will not produce another weeping cherry tree. A grafted tree takes advantage of the best properties of its scion and rootstock to create one “super tree.” Separated from each other, both the scion and the rootstock will fail to live up to what you have come to expect from the grafted product.
How to Grow Weeping Cherry Tree From Seed
Again, because this tree is grafted, the seed from it won’t come “true.” In fact, one reason why certain trees are grafted is that they do not come true to seed, so it is better to propagate them by “building” them, as it were. This way, you know what you’re getting. But the resulting seed will be just as unreliable as the parent’s seed.
Overwintering
Weeping cherry tree is reasonably cold-hardy. No extra care is required to overwinter it if you live in an area no colder than zone 5.
Common Problems With Weeping Cherry Tree
Weeping cherry tree is prone to attacks from insects and diseases. For example:
Borers
The weeping cherry tree is susceptible to infestations of borers (both adult and larval). A sign that you have a borer problem is sap leaking out of the trunk. Severe infestations are fatal and will necessitate tree removal. Your weeping cherry tree will probably survive a minor infestation as long as it is healthy and you continue to provide it with the sunlight, water, and nutrients that it needs.
Powdery Mildew Disease
Weeping cherries can be attacked by powdery mildew disease, a fungal disease that does little real harm to the tree but that mars its appearance. As when dealing with powdery mildew on any plant, there are several preventative measures you can take:
Strike a balance between keeping the soil dry and keeping it overly saturated. Soggy soil is a breeding ground for fungi.When watering, avoid getting the leaves wet.Irrigate early in the day, allowing excess water to evaporate prior to nightfall.Practice proper garden hygiene. Diseased vegetation should be immediately cut off and disposed of properly (not composted).
